[10], A 2018 study found in the U.S. an overall eastward shift of tornado frequency and impacts toward Dixie Alley. Science and environment reporter. NWS This trend is very visible once the data is mapped and because of this shift, the new highest frequency area for tornadoes is called Dixie Alley.

"Dixie Alley" is a colloquial term sometimes used for areas of the southern United States which are particularly vulnerable to strong to violent tornadoes. [10] Dixie Alley has been subject to numerous tornado outbreaks throughout history, including very intense outbreaks and those of very large spatial and temporal extent. [10], Dixie Alley is part of a region of enhanced tornadic activity extending between the Appalachian and Rocky Mountains,[11] but tornadoes and outbreaks in the Dixie Alley region exhibit some statistically distinguishable characteristics from the more well known Tornado Alley.

Categories of tornadoes (Enhanced Fujita scale), The 10 most deadliest tornado in the world, National Centers for Environmental Information. These tornadoes leave huge destruction trails. "Yes, when they occur in the Carolinas, it is predominantly in the Midlands swath.".
